For a more complete understanding of the invention and the advantages thereof, reference is made to the following descriptions, taken in conjunction with the accompanying figures, in which:
Among those benefits and improvements that have been disclosed, other objects and advantages of this disclosure will become apparent from the following description taken in conjunction with the accompanying figures. Detailed embodiments of the present disclosure are disclosed herein; however, it is to be understood that the disclosed embodiments are merely illustrative of the disclosure that may be embodied in various forms. In addition, all examples given regarding the various embodiments of the disclosure are intended to be illustrative, and not restrictive.
Throughout the specification and claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise. The phrases “in one embodiment,” “in an embodiment,” and “in some embodiments” as used herein do not necessarily refer to the same embodiment(s), though they may. Furthermore, the phrases “in another embodiment” and “in some other embodiments” as used herein do not necessarily refer to a different embodiment, although they may. All embodiments of the disclosure are intended to be combinable without departing from the scope or spirit of the disclosure.
As used herein, the term “based on” is not exclusive and allows for being based on additional factors not described, unless the context clearly dictates otherwise. In addition, throughout the specification, the meaning of “a,” “an,” and “the” include plural references. The meaning of “in” includes “in” and “on.”
As used herein, terms such as “comprising,” “including,” and “having” do not limit the scope of a specific claim to the materials or steps recited by the claim.
As used herein, terms such as “consisting of” and “composed of” limit the scope of a specific claim to the materials and steps recited by the claim.
All prior patents, publications, and test methods referenced herein are incorporated by reference in their entireties.
As used herein, all ranges are inclusive of endpoints unless otherwise specified.
As used herein, “between” when referring to a range shall include both mentioned endpoints (for example, “between 1 wt % and 15 wt %” shall include both 1 wt % and 15 wt %), unless otherwise specified.
The terms “substantially”, “approximately,” and “about” used throughout this Specification and the claims generally mean plus or minus 10% of the value stated, e.g., about 100 would include 90 to 110. Thus, as used herein, the term “about X” means X plus or minus 10%. For example, “about 10 wt %” means 9 wt % to 11 wt %.
As used herein, “wt %” refers to weight percent.
As used herein, the term “binder” refers to a compound that can bind a plurality of basalt particles together. The “binder” can either be liquid or solid.
As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) may refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
As used herein, where the expression “or a combination thereof” follows a list of more than two items, the expression is not limited to requiring presence of all of the items, but is also intended to encompass every subset thereof having any number of items from the list. Thus, for example, “at least one of Ca, Mg, S, or a combination thereof” encompasses (1) Ca, (2) Mg, (3) S, (4) Ca and Mg, (5) Ca and S, (6) Mg and S, and (7) Ca, Mg, and S.
As used herein, where a material is said to comprise a type of atom, the material is not intended to be limited to the elemental form of the atom in question, but instead is intended to also encompass compounds containing the atom. For example, “a material comprising B” is not limited to a material that includes elemental boron, but instead also encompasses a material that includes a boron-containing compound, such as a material comprising boric acid, borax, colemanite, potassium tetraborate, ulexite or a combination thereof.
In like fashion, as used herein “X is present in the product,” where X is an atomic symbol (e.g., “B is present in the product”), refers to the presence of X in the product but does not require that any or all of X be present in elemental form. For example, where the product includes boric acid, it can be said that “B is present in the product” irrespective of whether B is present in the product in elemental form.
As used herein, the following abbreviations, symbols, and expressions are defined as follows:
One embodiment pertains to using rock fines as carriers of (i) secondary macronutrients and/or (ii) micronutrients. In this embodiment, a product is prepared by a method that comprises obtaining ingredients and processing them. The ingredients include (a) rock fines and (b) a material, hereinafter referred to as “nutrient material,” that provides (i) secondary macronutrients and/or (ii) micronutrients. In a case where the rock fines themselves include secondary macronutrients and/or micronutrients, the nutrient material can be thought of as providing additional secondary macronutrients and/or micronutrients, thereby complementing the rock fines' secondary macronutrients and/or micronutrients. While two ingredients, namely rock fines and the nutrient material, have been described above, any other desired ingredient or ingredients may also be included (e.g., a binder, humic acid, etc., as discussed in more detail below). The product resulting from the method can be used as, for example, a soil amendment, fertilizer, etc.
In an embodiment a method comprises: (1) obtaining rock fines comprising at least one of basalt, metabasalt, diabase, rhyolite, andesite, meta andesite, granite, graphite, talc, silica, sand, perlite, or a combination thereof; (2) obtaining a binder; (3) obtaining a material comprising at least one of Ca, Mg, S, B, Cl, Cu, Fe, Mn, Mo, Ni, Zn, or a combination thereof; (4) combining the rock fines, the binder, and the material; and (5) forming the combined rock fines, binder, and material into a product.
In one embodiment, the method comprises combining the ingredients together, thereby obtaining (or forming) a “bulk form” product. In one embodiment, the combining comprises mixing.
In other embodiments, the forming results in a pelletized product (also referred to as a “pellet,” “granule,” “agglomerated particle,” “agglomerated granule,” or the like). A plurality of pellets may be produced in one batch of the method.
To obtain the pelletized product, in one embodiment, the forming comprises pelletizing, granulation, or compaction.
Granulation refers to a procedure involving steps comprising:
Compaction refers to a procedure involving steps comprising:
The drying, screening, and packaging for compaction are as discussed above with respect to granulation.
(iii) Flaked Product
In another embodiment, the forming results in a flaked product (also referred to as a “flake”). A plurality of flakes may be produced in one batch of the method.
To obtain the flaked product, in one embodiment, the forming comprises compaction as described above but using counter-rotating rolls to press powdery material of the ingredients into sheets which are crushed to form flakes (i.e., step (3) is “performing compacting of the mixture using counter-rotating rolls to press powdery material of the ingredients into sheets which are crushed to form flakes).
In one embodiment where the product is a pellet, the product's diameter (or average diameter of a plurality thereof) is 0.1 mm to 2 mm (which is referred to as “turf grade”). In another embodiment where the product is a pellet, the product's diameter (or average diameter of a plurality thereof) is 2 mm to 5 mm (which is referred to as “field grade”). Other ranges include 0.1 mm to 1 mm, 1 mm to 2 mm, and 0.5 mm to 10 mm. Combinations of the above-referenced ranges are also possible (i.e., any of the lower and upper limits mentioned may constitute a range). For example, other ranges include 0.1 mm to 10 mm. 0.5 mm to 2 mm, etc.
In one embodiment where the product is a flake, the product's largest dimension (or average largest dimension) are any of the ranges mentioned above.
Non-limiting examples of rock fines that may be used include at least one of basalt, amphibolite produced from the metamorphism of the basalt parent such as meta-basalt (also referred to as metabasalt), diabase, rhyolite, andesite, meta-andesite, granite, graphite, talc, silica, sand, perlite or a combination thereof. As mentioned above, the rock fines may, in and of themselves, include (i) secondary macronutrients and/or (ii) micronutrients. The rock fines may further include one or more essential plant nutrients, examples of which include Si, Co, and Se. Of these, Si is considered to be a beneficial element for plants, and rock fines having Si content are believed to make plants structurally stronger as well as to help mitigate infections and abiotic stresses. Thus, for example, some rock fines may themselves provide a number of secondary macronutrients, micronutrients, and/or essential plant nutrients, e.g., in one embodiment, the rock fines themselves provide, for example, (1) the secondary macronutrient Ca, (2) the micronutrients Fe and Mg, and (3) the essential plant nutrient Si.
In some embodiments, the rock fines include rock fines with sizes (e.g., diameter) or average sizes (e.g., average diameter) ranging from 2 μm to 0.5 mm, or 2 μm to 1.5 mm, or 0.01 mm to 0.5 mm, or 0.01 mm to 1 mm, or 0.01 mm to 2 mm. Combinations of the above-referenced ranges are also possible (i.e., any of the lower and upper limits mentioned may constitute a range), e.g., 2 am to 2 mm. Sub-micron rock fines may also be included. In some embodiments, 50%-95% of the rock fines have sizes falling within the above-referenced ranges or combinations thereof. In some embodiments, 60%-90% of the rock fines have sizes falling within the above-referenced ranges or combinations thereof. In some embodiments, 70%-80% of the rock fines have sizes falling within the above-referenced ranges or combinations thereof. Combinations of the above-referenced ranges are also possible (i.e., any of the lower and upper limits mentioned may constitute a range), e.g., 60%-70%.
In one embodiment, the rock fines are present in the product in an amount of 25-50 wt % with respect to the total weight of the product, or 40-75 wt % with respect to the total weight of the product, or 50-95 wt % with respect to the total weight of the product, or 75-95 wt % with respect to the total weight of the product. Combinations of the above-referenced ranges are also possible (i.e., any of the lower and upper limits mentioned may constitute a range). For example, other ranges include 25-95 wt %, 40-75 wt %, etc.
In some embodiments, the rock fines comprise at least one of basalt, metabasalt, diabase, rhyolite, andesite, meta-andesite, granite, graphite, talc, perlite, or a combination thereof. The aforementioned ranges may pertain to such rock fines.
As discussed above, one example of rock fines is basalt; however, metabasalt (which is an amphibolite produced from the metamorphism of the basalt parent material) may be used in addition to or instead of basalt. In other words, where the embodiments use the term basalt, they should be read as describing the use of basalt, metabasalt, or a combination of basalt and metabasalt.
As discussed above, when preparing the product in some embodiments, in addition to the rock fines, a second ingredient may be the nutrient material, which provides (i) secondary macronutrients and/or (ii) micronutrients. In one embodiment, the nutrient material comprises at least one of Ca, Mg, S, B, Cl, Cu, Fe, Mn, Mo, Ni, Zn, or a combination thereof. Among these, as explained above, Ca, Mg, and S are secondary macronutrients, and B, Cl, Cu, Fe, Mn, Mo, Ni, and Zn are micronutrients. Using such a material may make it possible to obtain a complete secondary macronutrient and/or micronutrient composition required by plants.
In some embodiments, the nutrient material may comprise at least one of a Ca-containing compound, a Mg-containing compound, a S-containing compound, a B-containing compound, a Cl-containing compound, a Cl-containing compound, a Cu-containing compound, a Fe-containing compound, a Mn-containing compound, a Mo-containing compound, a Ni-containing compound, a Zn containing-compound, or a combination thereof.

In one embodiment, the nutrient material is present in the product in an amount of 0.01-3 wt % with respect to the total weight of the product, or 3-20 wt % with respect to the total weight of the product, or 5-25 wt % with respect to the total weight of the product. Combinations of the above-referenced ranges are also possible (i.e., any of the lower and upper limits mentioned may constitute a range). For example, other ranges include 0.01-25 wt %, 3-25 wt %, etc. Where the nutrient material includes plural components (e.g., boric acid and zinc sulfate), the ranges are applicable to the nutrient material as a whole and/or to any individual component.
In some embodiment, in addition to the rock fines and the nutrient material, an additional ingredient or additional ingredients may be used to prepare the product. Such may include, for example, at least one of humic acid, a binder, a primary fertilizer (e.g., MAP), or a combination thereof.
In one embodiment, the binder may include, for example, clay, seaweed, amino acids, corn syrup, sucrose, molasses, starch, lignosulfonate, soy protein isolate or hydrolysate, corn steep waste, inorganic acid, organic acid, organic fertilizer(s), or a combination thereof. The binder may agglomerate together the rock fines (and any other ingredients) to provide a cohesive combination of ingredients. In one embodiment, the binder may be present in the product in an amount of 0.1-2 wt % with respect to the total weight of the product, or 1-2 wt % with respect to the total weight of the product, or 1-5 wt % with respect to the total weight of the product, or 3 wt % with respect to the total weight of the product. Combinations of the above-referenced ranges are also possible (i.e., any of the lower and upper limits mentioned may constitute a range). For example, other ranges include 0.1-5 wt %, 3-5 wt %, etc.
In one embodiment, the combining step further comprises combining humic acid with the rock fines, the binder (other than humic acid), and the material.
In some embodiments, the humic acid may be present in the product in an amount of 0.2-1 wt % with respect to the total weight of the product, or 0.5-3 wt % with respect to the total weight of the product, or 1-5 wt % with respect to the total weight of the product, or 3 wt % with respect to the total weight of the product. Combinations of the above-referenced ranges are also possible (i.e., any of the lower and upper limits mentioned may constitute a range). For example, other ranges include 0.2-5 wt %, 0.2-3 wt %, etc.
In some embodiments, one or more primary fertilizers (e.g., MAP) may be included as an ingredient of the product. As a result of the inclusion of one or more primary fertilizers, at least one of N, P, K, or a combination thereof may be present in the product. In such a case, in one embodiment, N may be present in an amount of 0.5-2 wt %, 1-3 wt %, or 3-20 wt % with respect to the total weight of the product, and/or P may be present in an amount of 0.5-2 wt %, 1-3 wt %, or 3-20 wt % with respect to the total weight of the product, and/or K may be present in an amount of 0.5-2 wt %, 1-3 wt %, or 3-20 wt % with respect to the total weight of the product. Combinations of the above-referenced ranges are also possible (i.e., any of the lower and upper limits mentioned may constitute a range). For example, other ranges include 0.5-3 wt %, 2-3 wt %, etc.
However, inclusion of a primary fertilizer in the product is not required; indeed, in one embodiment, the use of rock fines may eliminate the need to use primary fertilizers (e.g., urea, MAP, etc.) as carriers of secondary macronutrients and/or micronutrients. In this regard, where a primary fertilizer is used as a carrier of secondary macronutrients and/or micronutrients, (1) the secondary macronutrients and/or micronutrients may be applied to the primary fertilizer as a powder coating, which may lead to dusting, blending, and handling issues, (2) over application of primary fertilizer may lead to leaf burning, plant growth, and compatibility issues, (3) use of an NPK+S-based fertilizer may result in acidity issues, (4) a product using a primary fertilizer as a carrier of secondary macronutrients and/or micronutrients may lack the ability to provide Si to plants and to sequester carbon, and (5) some products may be highly concentrated (e.g., zinc oxide, 80 wt % Zn (i.e., zinc oxide is one of the most concentrated sources for zinc)) and lack uniformity on application and generate hotspots and undesirable effects in the field. Accordingly, it may be possible to omit primary fertilizers from the product or to use a small amount. To this end, in one embodiment, the product lacks N, or N may be present in an amount of less than 25 wt %, or less than 10 wt %, or less than 3 wt %, based on the total weight of the product. In one embodiment, the product lacks P, or P may be present in an amount of less than 25 wt %, or less than 10 wt %, or less than 3 wt %, based on the total weight of the product. In one embodiment, the product lacks K, or K may be present in an amount of less than 25 wt %, or less than 10 wt %, or less than 3 wt %, based on the total weight of the product.
One embodiment pertains to a method comprising: (1) obtaining rock fines comprising at least one of basalt, metabasalt, diabase, rhyolite, andesite, meta-andesite, granite, graphite, talc, silica, sand, perlite, or a combination thereof; (2) obtaining a binder; (3) obtaining a material comprising at least one of Ca, Mg, S, B, Cl, Cu, Fe, Mn, Mo, Ni, Zn, or a combination thereof; (4) combining the rock fines, the binder, and the material; (5) forming the combined rock fines, binder, and material into a product, and (6) applying the product to a field having seeds, plants, or a combination thereof planted therein.

In this example, a growth chamber study was conducted to study the effect of a boric acid formulation (labeled as “Blend 1” below) on plant growth and nutrient uptake. For this study, corn seeds (SC 1158AM brand) were planted in 2 L pots containing the following potting mix: 50% Pennsylvania Top Soil+20% Vermiculite+10% Perlite+20% sand. A base fertilizer comprising a water solution made from urea, monoammonium phosphate, and potassium chloride was prepared and applied at planting. In particular, this base fertilizer, which consisted of 120-100-100 NPK (i.e., nitrogen (N), phosphorus (P), and potassium (K)) pounds per acre equivalent, was applied at planting for fertilizer treatments (grower's standard practice (GSP)). The “Blend 1” formulation, which is detailed below, was applied at a rate of 45 pounds per acre equivalent for treatments receiving boron (e.g., boric acid). Approximately 300 ml of water was applied twice a week for each pot. Plants were harvested at the V4 growth stage (i.e., vegetative growth stage 4), and analyzed for above-ground plant biomass and nutrient uptake. Plant dry weight was determined by drying above-ground plant tissue for 24 hours at 220° F. Dried plant tissue biomass was ground to fine powder, digested and analyzed by a third-party lab using inductively coupled plasma (ICP) for elemental uptake.
As discussed above, the “Blend 1” or boron formulation used for this example is the following: 8% Boric Acid+2% Dry humics (Mesa Verde High Grade Pulverized)+88% Metabasalt+2% Molasses as Binder.
The results of this study, including the effect of the boron (“Blend 1”) formulation on plant growth, are shown in

While foregoing embodiments have been described as using basalt, the invention is not limited to basalt. For example, metabasalt, which is an amphibolite produced from the metamorphism of the basalt parent, may be used in addition to or instead of basalt. In other words, where the embodiments herein use the term basalt, they should be read as describing the use of basalt, metabasalt, or a combination of basalt and metabasalt. The wt % amount of basalt described above should be read as wt % amount of metabasalt in the case where metabasalt is used instead of basalt, and should be read as wt % amount of basalt and metabasalt combined in the case where metabasalt is used in addition to basalt.
Furthermore, in some embodiments, the soil amendment composition is substantially free of basalt, and in some embodiments, the soil amendment composition is substantially free of metabasalt. The expression “substantially free” refers to less than 3 wt % with respect to the total weight of the soil amendment composition.
